What is the initial password for the Mercury router? If admin can't log in, don't rush to experiment—the rules for the old and new models are completely different
Last week, my cousin asked me on WeChat: "Bro, what's the initial password for the Mercury router?" Everyone online says it's admin, I've lost ten times and still don't get it right." His unit is a Mercury D268G, included with broadband installed, and hasn't accessed the background for over a year. I immediately knew where the problem was—the answer he found was an old Mercury, while his was a new model. The rules were completely different. To clarify this, I also pulled out the old MW325R from my drawer, plugged it in, and tested both machines side by side. This article is based on the actual test results. To get straight to the point: Mercury routers don't have a 'unified initial password.' Old and new models have two different rules—first figure out which dial you're using on your machine, then discuss password .
first distinguish: is your Mercury model old or new
Mercury is a sub-brand under TP-LINK, sharing the same chip as TP-LINK. Its machines are cheap and abundant, and it is the most widely used broadband provider by carriers. Its login password comes in two eras: older models do come with default admin/admin settings; Around 2018, for security reasons, the new model remove the default password. The first time you enter the settings wizard, you are forced to set a 6-digit or longer management password, but after logging in, you recognize it.
You don't need to check the factory date to judge new or old models; just look at two places. First look at the sticker on the back of the router older sticker prints words like "Administrator Account: admin Administrator Password: admin," while the new sticker only shows the management address 192.168.0.1 and melogin.cn, with no password bar found. Second, look at the login box style enter 192.168.0.1 in the browser (I wrote a detailed article about how to access the address and what to do if it won't open), in the of the 192.168.0.1 login portal). The old model popped up with a "username + password" box, while the new version only has a "management password" box that doesn't even ask for the username. My MW325R has a two-row frame, while my cousin's D268G has a one-row frame, so you can tell them apart in one second.
the old Mercury: admin/admin, but three pitfalls that make you lose the right ones
Once it's confirmed to be the old model, try admin/admin. It sounds simple, but I've stumbled myself because the pitfall isn't in the password itself, but in the input.
The first pitfall is input method . When typing letters in the phone's Chinese input method mode, it might get the full-width admin character—looks exactly the same, but the router doesn't recognize it. When I made the machine for my mother-in-law, she was like this. I stared at the screen and didn't notice, so I switched to the English input method and retyped to pass. Before entering, check whether the input method icon is "Chinese" or "English." The second pitfall is the capitalization . Some mobile browsers automatically capitalize the first letter as 'Admin', and the password is case-sensitive. If you get it wrong, you still can't get in. The third pitfall is that add an extra space, which is not visible in the password box. When copying and pasting online answers, it's very easy to insert a space or line break.
If these three slots are still wrong, then most likely the password has been changed—the device is second-hand, the broadband installer made it on the spot, or someone at home has set it up before, all common. Don't keep battling on admins like this—skip to the 'Retrieve' section later.
new Mercury: There's no initial password at all, you set that password yourself
For the new model, you need to think differently: 's not the wrong password, but that you're looking for a password that doesn't exist. When you power on for the first time, the wizard will force you to set an admin password, which you casually enter is now the 'initial password.' My cousin insisted, "I never set it up," but later remembered—on the day of assembly, the technician had asked him to enter it once, but he had entered his own WiFi password, and after setting it, he forgot about it.
So the new model's recovery strategy is to guess my own old habits. Don't laugh, this move has a pretty good hit rate. Among the machines I've helped people use, the ones with the following settings are the most common:
- WiFi password repeat as is (most common, just to save trouble)
- admin, 123456, 888888 lazy passwords
- phone number, or the last six digits of the phone number
- your home number, birthday, but make sure the first letter is capitalized
Each one carefully plays twice (yes, to avoid slipping), and if it still doesn't work, just stop. Mercury's backend won't get a prompt or lock the phone if you keep typing errors, but it's pointless to waste it—my cousin is the admin who loses ten times in a row, just competing with himself. If you can't remember, take the next two paths.
two tricks to handle configurations without losing them, set reset first and last
Many people, once they can't remember the password, dig into the router's reset port, don't it yet. Reset is essentially factory reset, but the cost is the broadband account password, WiFi name password, speed limit rules for the TV box, and the child's internet time settings—all gone. If you forget the broadband password, you still have to call 10000 or 10086 to report the installation address, and you'll get in by the afternoon. Try two soft tricks first:
first trick: flip the Mercury router app. search for 'Mercury Router' in the mobile app store, install it, connect to the router's WiFi, and turn it on. Here's the key point: if your phone had linked this router back then, opening the app wouldn't require entering a management password , just the management interface—because the binding is stored on your phone, not the password. After entering, click "Tools" at the bottom - "Change Management Password" and set a new password. The backend will use the new password to access the website. My cousin was saved by this path. He installed the app during the build-up but never opened it again. He forgot the password but the binding was still there. I previously wrote a three-trick article about general ideas for recovering router background passwords. It also applies to machines other than Mercury. If you forget the router password see it, don't rush to reset.
second trick: check if the router is accessing the background end. there is a kind of 'wrong password' that actually means you entered the wrong door: your optical modem's management address is also something like 192.168.1.1, and entering the wrong address is the optical modem's login page. Using the Mercury password to enter the optical modem is definitely incorrect. To distinguish them, look at the page's appearance—the optical modem backend is filled with the words "LOID" and "Device Registration," and the Mercury backend has a large MERCURY logo. I wrote about the optical modem in the of the light modem indicator light self-check. Most people never need to touch it in their lifetime.
If neither of these moves worked, he would reset again. Method: Keep the router powered on, press the SIM ejector against the reset hole on the back for 8 seconds5 , then release the indicator light after flashing a few times when all the indicator lights flash. After resetting, connect your phone to the default WiFi (the name depends on the sticker, usually called 'MERCUS_ without password'), enter 192.168.0.1 in your browser or go melogin.cn the wizard to reset the settings. Before you start, prepare your broadband account password—this is the only hard requirement.
to wrap things up: the new and old models are a matching watch and follow the rules
Put together the results from the two machines in one chart. If anyone asks for the initial Mercury password in the future, just follow the chart:
| comparison items | older models (such as MW325R) | new models (D191G/D268G, etc.) |
| default password | admin/admin | No, the first time I set my own |
| login box style | username + password two lines | only one password box |
| sticker clues | printed with account passwords | only 192.168.0.1 and melogin.cn |
| first reaction | English input method admin | the habit of first setting up |
| is a dead end | Change your password in the Mercury Router app | same as left, if it still doesn't work reset |
The order is recorded in three sentences: First, look at the login box to distinguish between new and old models; The old model tried admin for input methods, and the new version was set for the first time; If none of these work, first check the app binding, and always save the reset last. In the end, my cousin's place was resolved with a single app move, taking five minutes in total. His D268G now has a management password he remembers, so I casually reminded him—don't set it like a WiFi password. If you try to guess one from the internet, it's like guessing two.
